Canvas Items Group: 8.4.1 Status: Open Resolution: None Priority: 5 Submitted By: Don Porter (dgp) Assigned to: Jeffrey Hobbs (hobbs) Summary: long, fat lines fail on Windows Initial Comment: # Source this into wish. Test with # # drawlines [makepts $count] $width # # where $count is number of points, $width is width of lines # in pixels. # # Works well on unix. Time required depends linearly on the # number of points, with thick lines (width>1) taking only # marginally longer than thin lines. # # On Windows, thin lines (width=1) work well, with time # required depending linearly on the number of points. # Thick lines are rendered slowly, with time required # increasing much worse than linear once the number of # points is more than say 100. On my Win98 box, with # Tcl/Tk 8.4.1, 'drawlines [makepts 1638] 2' raises # an illegal operation fault. More points than this # results in nothing being drawn. On Win2k, system # response becomes very sluggish as the number of points # moves into the thousands. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=112997&aid=630171&group_id=12997 |
